Izidingo ezintathu ezinkulu zebhethri lesitoreji samandla, ukuphepha kubaluleke kakhulu
Isitoreji samandla se-Electrochemical sithathwa njengendlela eyinhloko yokugcinwa kwamandla ohlelweni lwamandla esizayo, ibhethri nama-PC yinani eliphakeme kakhulu nezithiyo ekhasini eliphakeme, impilo ephansi kanye nezindleko eziphansi. Phakathi kwazo, ukuphepha kuyisihluthulelo. Abanye ochwepheshe bomkhakha bathi, manje isitshalo samandla esitoreji samandla se-electrochemical sikhula ngokushesha, kepha impikiswano yezokuphepha iyi-bottleneck yokuthuthuka kwayo okukhulu, isitshalo samandla e-Beijing Energy Storalier kanye ne-Tesla Australia Energy Resourde Project of the Indlworder Post embonini yamandla uzwile i-alamu.
Kuze kube manje, imibono ekhombisa ngokusheshisa ukuthuthukiswa kokugcinwa kwamandla okusha ibeka ukusungulwa kwamazinga wobuchwepheshe kanye nokuphathwa komlilo, kuqinisa ukuphathwa kwezokuphepha ngomlilo njengenqubo eyisisekelo; Ngokuphepha okuphezulu, izindleko eziphansi, ukuthembeka okuphezulu, impilo ende nezinye izici zentuthuko ende; Qinisekisa ukuphepha kocwaningo lobuchwepheshe be-Electrochemical Energy Seorth Reserty nokunye. IKhomishini Yezokuthuthukiswa Kwezwe kanye ne-National Energy, ibhodi yeNational Energy ukuhlela ukubelwa kweziteshi eziphephile ze-Electrochemical Ukugcina Iziteshi Zokugcina (okusalungiswa), ukuqinisa abaphathi wokuphepha kokugcina amandla.
Ukuphepha okuphezulu, impilo ende, ukugqamisa kwebhethri yebhethri ye-nickel-metal hydride
I-China ye-China Imboni Inkambiso Yezemininingwane ikhombisa ukuthi ukuphepha okuphezulu kwe-nickel-metal hydride kagesi, impilo yayo ende, i-electrode yayo eyenziwe nge-hydrogen storage, i-electroge active active asekelwa yi-hydrogen isitoreji i-alloy, ingenye yezinto ezizinzile, i-electrolyte yamanzi inokuhle Izakhiwo ze-Flame Retardant, ngeke ziqhume futhi zishise izingozi, ubuningi bebhethri monomer amandla afinyelela ku-140Wh / kg; impilo yokujikeleza impilo efinyelela ku-3,000, ukushaja okungajulile nokukhipha umjikelezo wombuso kuze kube yizikhathi eziyi-10,000 noma ngaphezulu; ingasetshenziswa izikhathi ezingaphezu kwe-10,000; ingasetshenziswa izikhathi ezingaphezu kuka-10,000. Izikhathi ezingaphezu kuka-10,000; kungagcina isilinganiso esiphakeme sokushaja kanye nokukhipha ku-40 ° C ~ 60 ° C. I-ToyotA Hev Car Global SALES ifinyelele ngaphezu kwezigidi eziyi-18, futhi ifakwe kabanzi ngamabhethri e-nickel-metal hydrid, akukaze kube khona icala elilodwa lezingozi zebhethri zokulwa, ukuphepha okuphezulu kwebhethri kuqinisekiswe ngokuphelele.
Ngaphezu kwalokho, ukushaja kwebhethri nokukhishwa kwe-diskarging ukuguqulwa kwamandla wamakhemikhali namandla kagesi, izinga lokushisa linomthelela omuhle ekuphenduleni kwamakhemikhali. Iziteshi zamandla ezitoreji zamandla zingaphandle kakhulu, izinhlobo eziningi zamabhethri zithinteka yimvelo kanye lokushisa, zikhawulela indawo yeziteshi zamandla futhi zinciphise amandla okugcina amandla. Amabhethri we-nickel-metal hydrid emazingeni okushisa aphansi kakhulu kanye nokushisa okuphezulu kwenkokhiso enhle kakhulu futhi esebenza kahle, ukuze indawo yesiteshi sokugcina amandla iguquguquke ngokwengeziwe, okulula, okungcono kokusebenza kwayo emncintiswaneni wezindlela ezihlukile zobuchwepheshe bebhethri " namaphoyinti afanayo ".
Eqinisweni, amabhethri e-nickel-metal hydrid kuhlelo lokusebenza lwemakethe yokugcina amandla abe yisakhiwo. I-2020, i-nickel-metal hydride ye-battery energy sergy stored coledgey Kuyaqondakala ukuthi uNilar ugxile ekuhlanganiseni kwamandla avuselelekayo namandla okugcina, amandla okulinda kanye nezinhlelo zokukhokhiswa izimoto zikagesi, ukutshala imali ukuhlanganisa inkampani kuzohlanganiswa nezinhlelo zemakethe yezentelelo kanye noma kwengqalasizinda . Ngokusho kwama-Frontiers ePolymer Science, iqembu likaStanford University lisungule ibhethri le-nickel-metal hydride (NI-MH) lamandla amakhulu okuvuselela amandla kanye nezinhlelo zokugcina, nezinzuzo ze-Ultra-Service Life, akukho bungozi Ukubaleka komlilo noma okushisayo, asikho isidingo sokulungiswa okujwayelekile, indlela enhle yokushisa okuphansi, nezindleko eziphansi. Iqembu likaCui lizokwakha iyunithi lendiza elinomthamo wesitoreji ama-2 megawatts ngo-2021, futhi amacebo wokwandisa amandla alo aze afike ezikhathini ezingama-20 ngemali ngo-2022.
